Downloaded this years ago and I come back to it every time I fall out of shape. Easy to follow and good motivation.

I love the timer however my runs are not syncing and I am unable to connect to my watch

I started with the 5K trainer and have worked my way up to the 13.1. Ran my first half this past December and did it in 2:13. I recommend this for anyone wanting to get started
